The Car Connection's Take

TCC’s Bottom Line
The 2018 Audi S6 stands with an impressive hand: quality interior, great performance, functional shape. It's possible to find better examples from other cars, but they all cost significantly more. The 2018 Lexus GS is a worthy rival to its German foes in terms of luxury and handling, but its engine lineup is falling behind the competition. The 2018 Mercedes-Benz E-Class goes to excess--the right kinds of excess--to preserve its best-of status.
